HINGE.

Specification of Letters Patent. Patented July 11, 1911.

Application led March 15, 1911. Serial No. 614,654.

To all whom "it may concern:

Be it known that we, WILLIAM A. I-InNN and MICHAEL D. HELFRICH, citizensof the United States, residing at Evansville, county of Vanderburg, andState of Indiana, have invented certain new and useful Improvementsin'I-Iinges, of which the following is a specification.

This invention relates to hinges, and more particularly to those forwatercloset seats and covers.

The present invention has for its object the provision of a hinge of thecharacter set forth which will be of strong, neat and durableconstruction and so compact and peculiarly arranged that it will permita closer roughing in or setting of the bowl and yet permit the seat andcover to stand in upright position, when raised, than has heretoforebeen possible.

IVith the foregoing object in view, we provide a hinge in which the leafor fitting for the seat is provided with an eccentric hub with whichcoopera-tes a spring-actuated friction member so that when the seat israised to any angle above approximately 45, it will be self-sustained,thus obviating accidental dropping of the seat with consequent damagethereto or to the bowl, and, further, the parts are arranged in a newmanner in connection with the hinge post, which latter is peculiarlyformed, as will more fully appear hereinafter.

In the accompanying drawings z-Figure 1 is a sectional elevation withcertain parts in full lines; Fig. 2, a detail view showing the parts ofone of the hinges and a part of the hinge for the cover in relativeposit-ion, the hinge post being broken away; Fig. 3, a detail viewshowing the cam on the seat fitting; and Fig. 4l, a front elevation withthe seat in section and broken away, the cover being raised.

The rear part 1 of the bowl is vertically apertured to accommodate theattaching bolts 2 for the hinge posts 8, the latter being provided withforwardly and upwardly extending parts t of tubular form provided with abridge or web 5 and with ears 6 which have apertures 7. The hingepintles 8 are received in the apertures 7 and are provided with collars9 which are adapted to abut the innermost ears 6, said pintles beingprovided with a portion 8a loosely received in a socket 10, in eachinst-ance, in the cover hinge 11 .to which the cover l2 iS Connected.

The cover 12 is, therefore, free to swing upand down and is notsustained in any position except when the seat is also raised.

The seat fittings 13 are secured to the under side of the seat 14 byscrews 15 and have upwardly extending parts 16 each provided with an eyeor aperture 17 through which the part 8b of the pintle loosely passes,and the parts 16 also have eccentric hubs 18 which are of such widththat, with the member 16,they occupy the entire space between-the ears Gof a given hinge post. A friction ring 19 receives the eccentric 18snugly, yet easily, and has a stein 20, which is received in an aperturein the web 5, a coil spring 21 encircling said stem between the ring 19and the said web and being of` such strength that the ring is held withconsiderable pressure in frictional engagement with the hubv 18.

The lid or cover 12 can be raised or lowered at willwithout disturbingthe seat 16, as it is journaled on the ends 8a. When the seat is raisedto an elevation of substantially 45 or greater, the eccentric hubs 18have turned to such position that they so act with the frictionrings 19as to insure retention of the seat and insure against liability ofaccidental dropping. Owing to the forward disposition of the hinge inrelation to the bolt 2, due tothe construction of the post 11, the seat,and cover can be swung past the vertical position, even though the bowlis set very close to the wall, so that the employment of our hingeresults in economy Vof space occupied by the bowl.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent, is :e

1. In a hinge, the combination of hinge members pivotally connectedtogether and a spring-actuated friction ring having an eccentricconnection with `one of said members.

2. In a hinge, the combination of hinge members pivotally connectedtogether, one of which has an eccentric hub, and a spring actuatedfriction` ring receiving and engaging the said eccentric hub.

3. In a hinge, the combination with hinge members pivotally connectedtogether, one of which has an eccentric hub, of a friction ringencircling said hub and provided with a stem, and a coil springencircling the stem and frictionally holding the ring Vagainst the saidhub.

4, The combination with a w-atercloset seat, of a hinge therefor, andspring-actuated means adapted for frictional coperation with the hingemembers to thereby hold the seat in any desired raised position whenelevated.

5. The combination With a Watercloset seat, of a hinge therefor havingan eccentric, and means frictionally engaging the eccentric to hold theseat in raised position When elevated.

6. The combination with a Watercloset seat, of a hinge therefor havingan eccentric,

and a spring-actuated brake member frictionally engaging the eccentricand adapted to hold the seat in raised position When 15 elevated.

In testimony whereof, We hereunto affix our signatures in presence oftwo Witnesses.
